I recently changed my site to https and the store has been slow ever since, especially the back-end. I saw the following errors:
So I deleted the Redux plugin and re-installed it from the WordPress.org plugin directory. That did not solve the problem: the back-end is still very slow. I activated the Redux Vendor Support plugin, so the CDN would not be used, but that did not solve the problem either.
Do you have an idea? Thanks!
